The Clean Air Act of 1990 initiated a tradable permit program for emissions of sulfur dioxide from coal-fired power plants. One effect of this policy was a large increase in the consumption of low-sulfur bituminous coal by coal-fired power plants. However, lowsulfur bituminous coal is also the ideal coking coal for steel production. The analysis presented here will attempt to determine how the ...
The facility is located four miles east of Hayden in Routt County, and consists of two BART-eligible boilers. Unit #1 is rated at 190 MW and is dry-bottom, wall-fired. Unit #2 is rated at 275 MW and is tangentially-fired. The Hayden boilers burn Colorado coal that primarily comes from two different mines in northwestern Colorado, the Twenty Mile Mine and the ColoWyo Mine. Coal characteristics a...
In this paper the bituminous water proof mortar, which has been used between the bricks in the Achaemenes monument of Tall-e-Ajori in Persepolis, has been analyzed by different instrumental chemical analysis methods, such as Fourier transform infrared spectroscopy (FTIR), X ray diffraction (XRD and X ray florescence spectroscopies (XRF). Moreover, due to identifying the chemical structure and e...
Analyses of samples of the raw materials locally available for use in the Eaton (Hopewell) Furnace indicate that the iron ore and bituminous coal were of good smelting quality while the limestone (flux) was not. The limestone had a much higher then desirable silica content and a low calcium content. The limestone was insufficient to the task of removing impurities introduced through the fuel co...
